2 DESCRIPTION Introduction The Model 20 is one of 9 very efficient, lightweight DC brushless rotary actuators produced by Tecnadyne. With continuous, variable speed rotation in both directions, the Model 20 is perfectly suited for many applications on AUV s, ROV s, manned submersibles and subsea tooling packages. Performance Characteristics As with all of Tecnadyne s rotary actuators, the Model 20 has multiple gearing stages. The first stage is always a 7/1 ratio planetary gearset; for extremely low output speeds multiple planetary stages are used. The final, output stage is always a harmonic drive and these are available in ratios from 30/1 to 120/1. Using different combinations of ratios, Tecnadyne is able to supply Model 20 s with 16 output speeds ranging from 1.5rpm to 75rpm. The maximum output torque of 20 ft-lbs (27 Nm) can be acheived at all speeds of operation, from 0rpm to the maximum rated speed (the 75rpm version is limited to 10 ft-lbs or 13.5 Nm). DC Brushless Motor Employing a 3-phase DC brushless motor that has been optimized for high efficiency and low noise, the Model 20 delivers exceptional reliability and high power in an extremely compact, lightweight and easy to maintain package. As with all Tecnadyne thrusters and actuators, the Model 20 motors are manufactured in the U.S. to the ISO 9001:2008 quality standard. Depth Rating Options The standard Model 20 configuration utilizes an oil filled housing for the DC brushless motor and gearing units, thus requiring that the electronics module be installed in a remote, 1-atmosphere housing (customer supplied). This configuration is rated to full ocean depth and the oil is compensated using flexible Tygon tubing for the cabling. Alternately, for shallow water applications, the Model 20 can be supplied with 1-atmosphere housings and internal electronics. This configuration is rated to 150 fsw (50 msw). Voltages Supported The Model 20 is available for operation at voltages of 24vdc, 48vdc, 70vdc, 85vdc, 100vdc, 150vdc, 200vdc, 250vdc and 300vdc. Alternate voltages are possible but will result in maximum output speeds not currently listed in this datasheet. DC power must be supplied by a well filtered battery bank, rectified and filtered AC or a regulated DC power supply with less than 10% voltage ripple. Speed & Position Control The oil filled configuration of the Model 20 can be supplied with several remote controllers depending upon the customer s operating requirements and the available space in the customer s 1-atmosphere housing (or Tecnadyne can supply a suitable housing). The most compact remote electronics option (HPFX & HPRX) is an open loop speed mode controller which accepts a +/-5v analog speed control signal. Alternately, Tecnadyne can supply an Advanced Motion Controls servo drive in two voltage ranges (AMCL & AMCH), that operate in current, velocity or position mode (when coupled with a suitable external position sensor). The 50m depth rated, 1-atmosphere version of the Model 20 can be supplied with an internal controller. This is an open loop speed mode controller accepting a +/-5v analog command signal. Electro-magnetic Brake Option The holding or backdrive torque of an unpowered actuator is 25%-50% of the rated torque, depending on gearing ratio. If higher holding torque is required, an optional electro-magnetic brake can be installed. Other Options Optional configurations include: housings made from hard anodized aluminum (standard), Type 316 stainless steel or 6Al4V titanium; several bulkhead type or cable end subsea connectors.

7 WHAT WERE YOU DOING 30 YEARS AGO? In 1985 Tecnadyne delivered its first thrusters, six Model 1020 s that were installed on the original RTV-500 built by Mitsui Engineering & Shipbuilding (MES) of Tokyo. Since that time, we have manufactured and delivered over 6,000 thrusters, including more than 600 of the Model And even though the Model 1020 that we build today incorporates over 32 design revisions to improve reliability, efficiency and maintainability that thruster is still 100% compatible with the Model 1020 that was installed on that first RTV-500 system more than 30 years ago. This means that, after 30+ years, MES (or any of our customers) can still purchase or repair a Model 1020 thruster to keep its fleet of ROV s working. And in those 30 years, the Model 1020 thruster has powered vehicles to the Titanic, that discovered JFK s PT-109 in the Pacific, that participated in record depth wellhead completions off the coast of West Africa, that discovered lost cities in the Black Sea, that have scoured the world s oceans for mines, and that have successfully completed thousands of routine subsea missions. And the Model 1020 thruster is still being installed on new ROV and AUV systems worldwide. And, like the Model 1020, Tecnadyne s twenty-one other thruster models have also served the offshore community with reliability, high performance and cost effectiveness but none for quite as long as the Model 1020 s 30 years. Tecnadyne is constantly developing and releasing new thruster models, with 4 new models released in 2010 and 4 models being released in It is Tecnadyne s commitment to its customers and to the subsea community that no vehicle system, be it an ROV, an AUV, a manned submersible or any other subsea system, will ever be made obsolete because the Tecnadyne thrusters installed on that system are no longer available for a reasonable and competitive price. So, for your next ROV, AUV or manned submersible build or purchase, be sure to specify only genuine Tecnadyne thrusters. You, your operators, your technicians and your customers will be glad you did for the next 30 years. QUALITY ASSURANCE Tecnadyne operates under a Quality Plan that is fully ISO 9001:2008 compliant. All electrical soldering is performed by technicians certified to the IPC J-STD-009 & IPC-A-610 standards. FINAL TEST & INSPECTION All Tecnadyne products undergo a rigorous set of final test procedures. Each thruster is operated at reduced power and full power in both directions for extended time periods. Each thruster is pressure tested and then subjected to an insulation breakdown test to identify leaks or other problems. Prior to shipment to the customer, each thruster is certified to perform correctly and to factory specifications. EXPRESS LIMITED WARRANTY Subsea thruster motors manufactured by Tecnadyne are warranted to the original Purchaser for a period of one year from the date of shipment from the factory to conform to Tecnadyne s specifications at the time of purchase and to be free of mechanical, electrical and physical defects in material and workmanship if the products have been installed, electrically connected, operated and serviced in accordance with Tecnadyne s instructions as listed in the Operations & Maintenance Manual accompanying the thrusters. Except for the express warranty set forth herein, Tecnadyne makes no other warranties or guarantees, express, oral, implied or statutory, regarding its subsea thruster products. All such warranties are expressly disclaimed to the extent allowable by law.
